Hypoxylon ? from Panama.
Esquivel-Rios Eduardo, 23-07-2013 23:37
Este Xylariaceae encontrado en madera muerta tiene ascocarpos planos, discoides, o de forma irregular,con una base estromatica negra. No se observan ostiolos ni estructuras en la superficie, los ascos de 80 - 100 micras ,  ascosporos ovoides, guttulados, de color marron claro o hialinos, 7 - 9 x 11 - 12 micras. Tiene el color y forma de Daldinia pero una sola capa de peritecios alargados, como Hypoxylon.--- Alguien puede ayudar...?

Re : Hypoxylon ? from Panama.
Hi,

it more looks like a member of Boliniaceae than of Xylariaceae. I think it is Camarops sp., but I do not know the species.

regards,

Re : Hypoxylon ? from Panama.
Hi Eduardo,
very interesting find but too poor information to identify it. I think it is a peltate Hypoxylon, maybe H. nicaraguense or something close.
You have to record the KOH reaction of a portion of stromatal surface, make more accurate measurements of ascospores, record the length of their germ slit and the dehiscence of the perispore in 10% KOH.
If I am asking too much let it dry and send it to me, half a stroma will be enough.
Cheers
Jacques

Eduardo: Junto con esa especie de Hypoxylon hay una Camillea parecida a C. billabiata.

Re : Hypoxylon ? from Panama.
Hola Eduardo,
it's a long way from Panama but I eventually received your specimens this morning...
This fungus is in very good condition and fits well H. polyporum (Starb.) Ju & Rogers based on its pale violet pigments in KOH and yellow brown ascospores with short germ slit and perispore indehiscent in KOH.
The other Hypoxylon is almost entirely immature but I managed to find some ascospores. They are typical of H. tortisporum Ju & Rogers, as is the olivaceous KOH reaction.
The last one on palm is Seynesia erumpens (Berk. & Curtis) Petr., a really distinctive taxon I had never seen before.
Gracias,
Jacques
